Cognitive overhead means a human being’s working memory gets stored at once and the amount of information we can deal with is extremely limited. Meaning the amount of information we wish to deal with should be dealt within the working memory. However, once we wish to overcome the working memory, the information cannot be processed but becomes lost or an overload occurs. This is cognitive overhead. Once too much information is provided at once, the learner gets the cognitive overhead meaning the lesson inefficient that becomes disturbance. The following theory is applied to a game, which the viewers get to experience their cognitive skills.
The work above uses visual and sound elements to find the right words. A brief explanation of the game is to find the exact number of word on each stage, which is provided to the player. Each level adds a visual or a sound element, which will overload the recognition skills of the user.
